Most rulers do not measure twelfths of an inch, therefore measurements have been rounded to the closest standard measurement. For exact conversions, I recommend you obtain a ruler that divides an inch into 12 parts.
Ceiling Heights: 8-12’ depending on time period and style One inch scale = 8-12” Half inch scale = 4-6” Quarter inch scale = 2-3”
Door Height: 6’8” One inch scale = 6 11/16” Half inch scale = 3 5/16” Quarter inch scale = 1 21/32”
Door Width: 30”-36” One inch scale = 2 1/2″-3″
Chair Seat Height: 18” One inch scale = 1 ½” Half inch scale = 3/4″ Quarter inch scale = 3/8″
Table Height: 30” One inch scale = 2 1/2” Half inch scale = 1 1/4″ Quarter inch scale = 5/8″
Counter Height: 36” One inch scale = 3” Half inch scale = 1 1/2″ Quarter inch scale = 3/4″
